I bought a garmin nuvi 680 in a yard sale,functional is ok,but need pin can you help

I have a Nuvi 680. I bought a 4G SD card for more storage. Yesterday Garmin sent me a new map to install and now the Nuvi is telling me there is not enough space. Can't be! Nothing was ever installed onto the SD card since I only put it into the Nuvi today. Help, what am I doing wrong?

You actually have two problems; you won't just need the pin code, but will need to know at which location the pin code was set.

The system is designed to make stolen Nuvi's useless and cannot be bypassed without internal hardware changes which will cost more than replacing the unit. Unless you can obtain the pin code AND take the Nuvi to the location it was originally entered then it's totally unusable.

Chalk it down to experience and resell yours as being for spares or repairs.

Try to calibrate the touch screen .

If not send it to a repair centre they will fix the touch screen for you.

There is NO master reset code. Whoever told you this was wrong. You have to use your security location to unlock it. Otherwise, you have to send it in to Garmin with the original receipt from an authorized Garmin dealer. This is to prevent use of the unit in case of theft.

I think you have to send it back to Garmin. Liam

not sure if this link will help you but have a look.

Here's your options:

1. Enter the correct PIN.
2. Go to the secure location where the PIN was set and it won't ask you for a PIN.
3. Send the unit back to Garmin to be unlocked.

Sorry but there is no master reset. The PIN is written into memory that can not be erased. I have had success in unlocking Nuvi's but I will only do it for people who have a valid purchase receipt from a major retail chain and if they can provide me with their Garmin registration info so I can verify that they are the rightful owner.

There are too many of these units out there that are stolen and the culprits are looking for a way to bypass the PIN. This is why Garmin added this feature to their GPS's.

The only ways to unlock a PIN locked Garmin are to enter the correct PIN number, or take the unit to the location at which the PIN was initially entered. Your only other option is to send the unit to Garmin.
